本文根据设计搅拌机的需要,采用结构化程序设计方法,编制了计算自落式搅拌机中生混凝土的重心以及混凝土和搅拌筒一起对支点的力矩的计算机程序。本程序能计算搅拌机轴线对水平面成任意角时,一定量的混凝土的重心和力矩,大大减少了手算的时间,为搅拌机的优化设计提供了可能。 In this paper, according to the design of the mixer, a structured program design method was used to compile the computer program for calculating the center of gravity of the raw concrete in the self-loosing mixer and the moment of the concrete and the mixing drum to the fulcrum. This program can calculate the gravity center and moment of a certain amount of concrete when the axis of the mixer is at an arbitrary angle to the horizontal plane, which greatly reduces the hand-counting time and provides the possibility for the optimal design of the mixer.
